that is not the hot water heater bypass. That is your suction from the water tank in that set up . turn those knobs opposite and you can stick the open end of the one hose into a jug of pink non tox antifreeze to suck from the jug.
the bypass forthe water heater are connected to the back of the heater itself. Look outside for the heater and it is inside in that area. shut off the heater unrill you are sure there is water in it ..
